Pitt's Head

Pitt's Head (Welsh: Carreg Collwyn) is a distinctive rock located at grid reference SH576515, close to the A4085 road in Gwynedd, Wales.

Its distinction lies in a resemblance to the profile of politician William Pitt the Younger.

Located as it is near the base of one of the paths to the summit of Snowdon, Pitt's Head Halt was a station on the original Welsh Highland Railway, also marking the highest point on that railway.

This is an Ordovician acid ash-flow tuff which outcrops on the northern flanks of Snowdonia.

Collwyn ap Tango was said to be Lord of Eifionnydd, Ardudwy and part of Llŷn.
